I'm now a Proud "Real" member of the 20 mph club! Stuck at 19 for months and months - increased tire pressure and my "goped" broke the "Speed Barrier"!!!!!! I hope my Tires are Speed Rated ;-/. --- I'm so proud of her ;-). .................... outside of endless acutriments (like my mirrors jigglying loose and windscreen mounts popping off after every other ride) having to be re-bolted on, her fundamental mechanicals are still sound at mile 300 and 7 months....knock on wood. only complaint (other than reattaching stuff which get old (I think I've finally fixed this though) is she sure is LOUD - even though 4-stoker. .................time for the "speed kit", to reach the next mountain - 25 mph!
